Young scientists, sisters, and theologians of the “green generation” reflect on “saints”, canonised and not, who offer hope and inspire us towards ecological action. “In the community of saints, all together are companions in memory and hope. Together, all together, they are becoming something strange and growing and great, instruments of change. Green Saints for a Green Generation taps beautifully into this dynamic for the sake of our suffering Earth, which cries out for no less”.
